FOR AMINIFER A— HERON-ALLEN AND EARLAND. 161 



At Station 2 a remarkable specimen was found, heart-shaped, with an ento- 

 solenian aperture at each extremity. The surfaces plane, slightly sloping from 

 the thickest extremity or point of the heart to the base. The prmcipal aperture 

 aj)pears to be at the pointed end. 



357. Lagena hicarinata, var. villosa, nov. PI. VI., figs. 10-12. 



Stations 2, 3, 6. 



Characters similar to the type, but the marginal edges are thickened with shell- 

 substance, granular in structure, giving the appearance of a fur trimming round 

 a clear test. Confined to the N.Z. area and rare. The best specimens at Station G. 



Size: — Length, •23mm.; breadth, •20mm.; thickness, •12mm. 



358. Lagena hicarinata, var. spinigera, nov. PL VI, figs. 6, 7. 



Lagena hicarinata, Sidebottom, 1912, etc., LSP. 1912, p. 419, pi. xix, fig. 27. 



Stations 17, 23. 



One specimen at each Station ■ referable to Sidebottom"s form as referred 

 to above, characterized by the weakly developed and widely separated carinae 

 and the presence of a single conspicuous basal spine, to which no reference is made 

 in his text, though it is clearly indicated in the drawing. The spine in ' our 

 specimens are very much more developed than is shown in his figure. 



Size: — Total length, •27 mm. (including spine, -03 mm.) ; breadth, -09 mm.

Fairly frequent. This appears to be one of the typical N.Z. Foraminifera.

Stations 2, 3, 5-8, 10, 11, 16-18, 22, 27, 36, 45, 48. 



Universally distributed, most frequent in the N.Z. area, w^here two distinct types 

 occur at most of the Stations, one being nuich longer than the other, and usually with 

 poorly developed keels, forming a variety intermediate between Chapman's 

 L. enderbyensis and the type. At Station 6 in the N.Z. area specimens occur of a 

 quadrate circular type, with spinous base, referable to Millett's variety, cakar (M., 

 1885, etc., St. E. 1898, p. 175, pi. 0), but differing from his specimens m the absence 

 of the produced neck, as figured in the original drawing, and in the more quadrate 

 outline of the test, as figm-ed in his Malay paper (M., 1898, etc., F.M. 1901, 

 p. 626, pi. xiv, fig. 18), and figured by Sidebottom, without a varietal name, 

 from the Pacific (S., 1912, etc., LSP., 1912, p. 416, pi. xix, fig. 14). The finest 

 development is attained in the deep-water Stations, notably Stations 16-18, where
